NAME

       memfrob - frobnicate (encrypt) a memory area

SYNOPSIS

       #define _GNU_SOURCE             /* See feature_test_macros(7) */
       #include <string.h>

       void *memfrob(void *s, size_t n);

DESCRIPTION

       The  memfrob() function encrypts the first n bytes of the memory area s by exclusive-ORing each character
       with the number 42.  The effect can be reversed by using memfrob() on the encrypted memory area.

       Note that this function is not a proper encryption routine as the XOR constant is fixed, and is  suitable
       only for hiding strings.

RETURN VALUE

       The memfrob() function returns a pointer to the encrypted memory area.

CONFORMING TO

       The memfrob() function is unique to the GNU C Library.
